Abstract
A sea anchor may be lifted from the sea bottom by remotely inflating an inflatable float connected to the anchor. The inflated float provides a buoyant lift force that automatically lifts the anchor to the water surface or assists a person in lifting the anchor to the surface. The anchor may be lowered to the sea bottom by venting air out of the float from a remote point on the water surface.
Claims6
A raisable-lowerable anchorage mechanism comprising:
- an anchor adapted to assume an operating position on the sea bottom or an inactive raised position at the sea surface;
- an inflatable-deflatable float means carried by said anchor;
- a surface vessel operable to support the anchor in its raised position;
- air pressure-generating means on said vessel;
- air conduit means connecting said air pressure-generating means to said float means, whereby said float means can be inflated or deflated from the sea surface;
- and
- said anchor comprising an elongated rod, and said float means comprising an annular float encircling said rod.
